NI-USRP 2921

[wicak]

Hai, currently I'm trying to build a transmitter for IEEE 802.15.4, just for the PHY.

The standard specify the symbol rate for 802.15.4 is 62.5 kSymbol/s, Bit rate 250 kb/s

How I set this parameter in USRP.

I knew that 802.15.4 uses OPSK for modulation, but the pulse shape, I have no idea about this.

Does anyone, could enlight me about this.

Any comment would be appriciated, since I'm new to LabVIEW

And, I wonder in the ni-USRP Write data Tx, the transmission order, the array[0] or the last array is transmitted first?
